💀⭐⭐⭐Bouncing grenade
Highly unpredictable weapon, still it's much useful due to its ability to bounce and get to unreachable areas. Already banned by Geneva Conventions, but zombies won't complain.
💀⭐⭐⭐Radio grenade
Remotely controlled ball of death. Activate the detonator right in time or wait for 12 seconds for auto detonation.
💀⭐⭐⭐UV grenade
Latest warfare technology against zombies. Extreme UV radiation immediately burns their guts down, but seems to be harmless for humans.
